+++ This bug was initially created as a clone of Bug #824898 +++
I tried to add an as7 manually in the release branch and it failed with the red
bar. So I wen to the message center to see what is going on.
Remember that I have a 1920*x screen. So pretty wide. And still I had to scroll
8k pixels to the right in order to see the
real message that the plugin wanted to tell me.
For the user this is a usability issue.
We should in the first "Details" line only show the message from the inner most
exception (what is on the right side of the screen)
And then lower down (after some newlines) show what we have today.
Bonus points for replacing each '->' in the original details line with a line
break (or adding the line break before '->'
